Park Brake on Warning driving me crazy!

So, I have a '14 T800 that is rigged up in Hot Oiler Trim.... While I sit and do my jobs, the truck has the pto switch kicked on and engine reved up, and the Park Brake on warning chime just dings away. I need to get this to stop without having to sit onsite without my park brakes on....

As defined in the manual, this alarm comes on when the park brake is set, and the vehicle speed is greater than zero, or throttle input is over 10%...

How do guys sleep in the winter with their trucks revved up to keep warm up north? This is a silly alarm, and if anyone can help me out I would appreciate it.

 

I think you're missing the point.... I need to run the truck to power my equipment.... While parked and revved up, so the alarm will be chiming, even though the truck is sitting there doing what it was built to do... There must be some aftermarket way or something to turn this alarm off so that I don't need to listen to it all day long.

 

Is there a device i can buy to hook up to my truck and set my own parameters on stuff like this?
